Snowpit Observations
More detailed information about the snowpack: 

Skinned up NE aspect from Convict Lake Resort.  Dug a quick pit at 9000 ft on a 35 degree N aspect.  Skied Northern chutes a couple of times then back out the E facing morrain to the Resort. 

Total snow depth was 190 cm, probed as deeper (210 cm) a bit lower down.  Dug the pit to 125 cm.  Layers were from the top 0 - 15 fist, 15 - 42 4F, 42 - 125 gradual change from 4F+ to 1F.  We did note that there was a harder layer at least 5 cm thick, looked like large (1-2 mm) frozen melt forms, starting at 125.  Test results were CT25 at 50 cm Q2, CT27 at 55 cm Q3. 

We could see previous wind scouring on W facing slopes, there was no wind today.  Also saw scattered roller balls (some large) but no entrainment or fanning on E and NE slopes, looked like they were from yesterday.  Skiing in on the N aspect was great.  Really good light powder most of the way down, heavier lower down.  Skiing on the E slope at 3 pm was very heavy and had a little bit of breakable sun crust.  Definitely turned since this morning in the sun and warmth.  However the upper NE slopes did not seem to develop new roller balls or show the effects of rapid warming.
